There are several hiking trails at Long Hunter designed to provide pleasant walking experiences for all. Among the more popular is the two-mile loop Lake Trail around Couchville Lake. It is also home to the Jason Allen Arboretum Trail at Couchville Lake that weaves its way through the first certified arboretum in a Tennessee State Park. Visitors along the Jason Allen Arboretum Trail will see 44 stenciled leaves on the barrier-free, hard surfaced path that signify where the different trees are marked. These stenciled leaves were created by Tina Turbeville, a Friend of Long Hunter, who worked with Jason and Fred Dickson, another Friend of Long Hunter, to carefully apply the leaf stencil to the Arboretum trail. Unlike most sites where trees are planted for the sole purpose of creating an arboretum, these trees were already occurring naturally around Couchville Lake. This provides a wild feel and makes the arboretum site even more special.
